Hi everyone!

With DevStack, there are some tutorials in which you have a single virtual machine with all functions of OpenStack (Controller, Network and Compute).

I want to separate the network function, and use Neutron in other node (Network Node), like in the OpenStack Architecture: (image description)

What services must be activated in controller node with DevStack? In the figure, we can see that these services are Neutron Server and ML2 Plug-in, but how they are activated? How do they connect with the network node?

I suppose that is necessary to correctly configure local.conf file in controller node and in network node...

Thanks in advance!

Actually, there is an option which will setup restart able Openstack Kilo services on Controller,Network,Compute Nodes instead bunchs of daemons. It's RDO Kilo on CentOS 7.1 ( Fedora 21). View

Yes , I described a model based on libvirt's sub nets and using nested KVM, however it works same way on physical boxes and networks. I cannot realize what for people need Devstack when setup is related with stable branches. I do need Devstack when recent nova commits have to be tested.

I just suggest alternative solution which can be released via Multi-Node deployment performed by packstack utility RDO Kilo (or Juno) in meantime on CentOS 7.1 && Fedora 21 ( F22 soon )
Detailed instructions and answer-file for Controller,Network,Compute (s) Nodes setup:-
